Just adding to the data, we did it once and got twin girls on the first go. Instant family. We then got a "surprise" (my wife says I'm not allowed to use the word "accident") three years later with a naturally conceived girl.

Chaps - when the docs tell you you're infertile and need IVF, don't assume you'll be infertile forever. Have a vasectomy and "make it so".

Good luck with your IVF, if it works, it'll totally be worth it. Probably.
